random draw for heat races with passing points. the top 40 in passing points go to the qualifying races with top 24 inverted. this means that the first 6 starters in each qualifier are inverted based on heat race points. it seems that they are running the C mains before the qualifiers. these are the guys with the least amount of points. the top 4 in each tag the back of the B's. after the qualifying races, the top 16 in points (combined heat race and qualifier) are locked into the A and the rest start straight up in the B's. Top 4 from the B's go to the A. The A is also started straight up...no inversion.
